Question

Pearl divers in the South Pacific will often hyperventilate before diving into the water in search of oysters that contain the pearls. By hyperventilating, the divers exhale repeatably before entering the water. Explain why hyperventilating is an important step prior to their dive,

Answer 1

Answer: Due to the hyperventilation the carbon dioxide content in the body get reduced. And it also increases the oxygen content. This procedure is very useful for divers to hold the breathe under the water and it enlarge the time of urge to breathe again because due to the high carbon dioxide level create the feel of urge to breathe. If the level of carbon dioxide is reduced that urge also reduced. But it is a life threatening procedure because it leads to loss of consciousness under the water. It may also causes cardiac arrest, blood supply to the brain get reduced etc.
